Title: Decontamination method for radioactive waste
Inventor: HETA KATSUTOSHI
IPC: G21F9/28
Filed: 1990-08-31
Abstract: PURPOSE:To easily and positively perform decontamination by freezing a metallic waste with liquid nitrogen, and grinding it by impact shocks. CONSTITUTION:A radioactive waste 1 is thrown from above a refrigerating breaker 2. The waste 1 is immersed in a liquid nitrogen bath 3 filled with liquid nitrogen supplied from a liquid nitrogen tank 4, and frozen closer to 196 deg.C. Then a rotary-shearing type impact breaker 5 imposes impact shocks on the waste 1 to break it into about 30mm square. Further, the broken wastes are sent to a decontaminating device 6 to be decontaminated. Besides, since the objects to be measured are broken, blasting decontamination method, elctrolytic grinding decontamination method, redox decontamination method, chemicals-immersion decontamination method, etc. are entirely applicable to the broken wastes. Thereafter, the decontaminated broken wastes are sent to a radioactive contamination quantity measuring device 7 in order for the quantity of remaining radioactivity to be measured. At this time, the objects to be measured are broken, the measurement can be easily and positively performed.

Abstract: PURPOSE:To attain the smooth and highly efficient communication between processors by deciding autonomously the propriety of receiving the communication information from other processors based on the processor state, i.e., the contents of a register and informing a transmission processor of the reason for rejection of receiving the communication information if decided to 'No'. CONSTITUTION:A register 206 (406) which stores the state of a processor 10 (30) contained in an inter-processor communication equipment 20 (40) grasps the normal state, the congestion state, the initialization state, the faulty state, etc., of the reception processor 30 (10) based on the contents of the register 206 (406) in the reception mode of the equipment 20 (40) to decide the propriety of reception. Thus the propriety of reception is decided in accordance with the degree of congestion and the priority of the communication information if the processor 10 (30) is kept in a congestion state. When the rejection of receiving the information is decided, the equipment 20 (40) informs the transmission processor 10 (30) of the reason for rejection. Thus the processor 10 (30) can decide the propriety and the necessity for retransmission of the information based on the received reason. Meanwhile the processor 30 (10) can reject the reception of the information without performing any reception process. Thus the smooth and highly efficient communication is attained between both processors.
